Abstract

A device and a method for remote maintenance of an electronically controllable prosthesis (1) are provided. The prosthesis comprises a controller in which operating and/or movement data characterizing the prosthesis are detected and are then transmitted to a remote maintenance device (20) with a storage and evaluation unit (20). Remote maintenance of the prosthesis using the detected data is possible via a remotely located remote control unit (23) that can access the storage and evaluation unit via the telephone network. Corrected operational data are transmitted from the storage and evaluation unit (20) back to the controller of the prosthesis.

Claims

1. A device for remote maintenance of an electronically controllable prosthesis, the prosthesis comprising a controller for detecting movement data characterizing a movement of the prosthesis wearer and for outputting of control data to the prosthesis, the remote maintenance device comprising:

a first data transmission device, which can be linked to the controller of the prosthesis, through which movement and/or control data can be transmitted bidirectionally between the controller of the prosthesis and the first data transmission device;

a second data transmission device for transmitting movement and/or control data to a remotely located control unit and for receiving data from the remote control unit; and

a storage device for storing movement and/or control data;

wherein the remote control unit is linked to the second data transmission device via a data transmission network.

2. A device in accordance with claim 1, wherein the prosthesis further comprises one or more rechargeable batteries and wherein the device further comprises a charging component for charging the rechargeable batteries when the prosthesis is connected to the device.

3. A device in accordance with claim 2, wherein the controller of the prothesis further comprises a clock and the device further comprises an externally controllable clock to enable synchronization with said clock provided in the prosthesis.

4. A device in accordance with claim 2, further comprising a display/input unit for displaying the data concerning the prosthesis and for entering commands.

5. A device in accordance with claim 2, wherein the device is structured and arranged so that the controller initiates communication via the second data transmission device with the remote control unit when the movement and/or control data deviate from a default data.

6. A device in accordance with claim 1, further comprising a controller that controls an evaluation and/or transmission of the movement and/or control data in accord with a preset program.

7. A device in accordance with claim 6, wherein the controller of the prothesis further comprises a clock and the device further comprises an externally controllable clock to enable synchronization with said clock provided in the prosthesis.

8. A device in accordance with claim 6, further comprising a display/input unit for displaying the data concerning the prosthesis and for entering commands.

9. A device in accordance with claim 6, wherein the device is structured and arranged so that the controller initiates communication via the second data transmission device with the remote control unit when the movement and/or control data deviate from a default data.

10. A device in accordance with claim 1, wherein the controller of the prothesis further comprises a clock and the device further comprises an externally controllable clock to enable synchronization with said clock provided in the prosthesis.

11. A device in accordance with claim 10, further comprising a display/input unit for displaying the data concerning the prosthesis and for entering commands.

12. A device in accordance with claim 10, wherein the device is structured and arranged so that the controller initiates communication via the second data transmission device with the remote control unit when the movement and/or control data deviate from a default data.

13. A device in accordance with claim 1, further comprising a display/input unit for displaying the data concerning the prosthesis and for entering commands.

14. A device in accordance with claim 13, wherein the device is structured and arranged so that the controller initiates communication via the second data transmission device with the remote control unit when the movement and/or control data deviate from a default data.

15. A device in accordance with claim 1, wherein the device is structured and arranged so that the controller initiates communication via the second data transmission device with the remote control unit when the movement and/or control data deviate from a default data.

16. A method for remote maintenance of an electronically controllable prosthesis, the method comprising the steps of:

a) detecting data characterizing the operation of the prosthesis while the prosthesis is being worn;

b) transmitting the detected data to a remote maintenance device comprising a data storage and evaluation device;

c) accessing the data stored in the data storage and evaluation device through remote control unit via a data transmission network;

d) assessing and, when necessary, updating the stored data;

e) transmitting, when necessary, updated data to the data storage and evaluation device via the data transmission network; and

f) transmitting the updated data from the storage and evaluation device to the prosthesis.

17. A method in accordance with claim 16, wherein the data transmission network is a telephone network.

18. A method in accordance with claim 16, wherein the detecting step comprises detecting movement data over a preset period of time and, the method further comprises evaluating the movement data in the data storage and evaluation device and correcting the data characterizing the operation of the prosthesis using the movement data.

19. A method in accordance with claim 16, further comprising removing the prosthesis to carry out the remote maintenance.
